Our Mental Math (Add/Subtract) lesson plan teaches students strategies for mentally doing addition and subtraction of two-digit numbers. During this lesson, students are asked to solve practice problems using the techniques taught in this lesson, including both word problems and traditional problems. Students are asked to show their work and describe the strategy they used.
At the end of the lesson, students will be able to compute basic addition and subtraction with two-digit numbers using mental math strategies.
